Title: Air conditioner
Inventor: NAKAMURA SETSU
IPC: F25B13/00
Filed: 1991-05-30
Abstract: PURPOSE:To prevent the dry-up of refrigerating machine oil for a compressor by a method wherein the opening degree of a valve for a flow rate control device is increased when a difference between a temperature at the downstream of a heating means for a bypass passage of an accumulator and the suction pipe of the compressor and the low-pressure saturating temperature of a suction pipe of the compressor has become larger than a predetermined value. CONSTITUTION:When liquid refrigerant in an accumulator 4 is reduced and the level of the same is lowered than the take-out position of a bypass passage 41 and gas refrigerant flows into the bypass passage 41, the gas refrigerant becomes overheated gas refrigerant by heating in a heating means 43 and, therefore, a difference between the temperature of a temperature detecting means 44 and the low-pressure saturated temperature becomes larger than a predetermined temperature difference. Accordingly, the opening degree of the valve of a fourth flow rate control device 17 or a third flow rate control device 15 becomes larger than a predetermined amount whereby liquid refrigerant flows into the accumulator 4. According to this operation, the liquid refrigerant of the accumulator 4 will never be dried up whereby the damage of a compressor due to the increase of overheated degree of the suction gas refrigerant of the compressor, the increase of the discharging temperature of the compressor and the deterioration of lubricating property of the refrigerating machine oil can be prevented. On the other hand, the dry-up of the refrigerating machine oil for the compressor due to the adhesion of the refrigerating machine oil to the inner wall of the accumulator 4 can be prevented.
